Effect of Surgical Approach on Postoperative Bleeding in Patien Arthroplasty

The presence of bleeding and pain after prosthesis surgery Hip injuries can affect the patient's condition in the postoperative period increasing the length of hospital stay and slowing down the rehabilitation process. It is hypothesized that there are differences in terms of postoperative bleeding, Postoperative pain and hospital stay time between different approaches surgical procedures in the treatment of hip osteoarthritis with arthroprosthesis. The adoption of a Surgical approach that can reduce bleeding and pain could reduce the length of hospital stay in patients undergoing hip arthroplasty. The primary outcome will be blood loss calculated on the basis of hemoglobin (Hb) on the third postoperative day. Secondary objectives are postoperative pain assessment with questionnaire VAS and length of hospital stay according to surgical approach used (anterior Vs. posterolateral route). Also evaluate Any adverse events. Adult patients who will undergo surgery of hip arthroplasty. The inclusion criteria are: * adult patients with coxarthrosis who are candidates for surgery hip arthroplasty * Signing of the Informed Consent and consent to collaborate in all study procedures. The exclusion criteria are: * Minors * Pregnant women (self-declaration) * patients with BMI ≥ 30 * Non-acceptance of informed consent * Patients with prior unilateral hip reconstructive surgery or Contralateral
